Origin, sound and short forms
Our story of Cyd
The letters Cyd- open an old Greek place-name, Kydonia, a city on Crete, and the Romans called the fruit that came from there the Cydonian apple. Worn down through Latin and French, that phrase became the English word quince, the hard golden fruit that turns rosy when it is cooked. Cyd has no recorded tie to it; it is a short form of a longer name. But its opening carries that little journey from a Cretan city to an English orchard.
